APPARATUS FOR THE SEPARATION OF VOLATILE PRODUCTS FROM SOLID CAR-LBONACEOTIS MATERIAL. l

Application filed August 20, 1925. Serial No. 51,392.

The present invention appertains to the art of separation of volatileproducts from. solid carbonaceous material, and has forits purpose toseparate from shale rock by heating, crudeoil, andall the by-products ofammonium sulphate, potash, etc. and torecover from spent shale the dyevstuli', paint fillers,

' etc.

The object of the invention is to provide a construction which isbothsimple and durableas compared with the intricate apparatus now in commonuse.

Another importantobject ofthe invention I is to. provide an apparatuswhich is exceedingly efficient andreliable in its operation, and is ableto withstand, the intense heat necessary in the ,cookingprocess. I Viththe apparatus now in use it is necessary, every five or SlX weeks, toreplace important parts at a high cost, whereas the present inventionobviates these periodical costs and consequently reduces the upkeep.This end is accomplishedby the introduction of a nonnvarping steelcylinder or cylindrical tank which, in actual practice, has withstood aheat of fifteen hundred degrees Fahrenheit without warping or burning.

With the above and numerous other ob jects in view as will appear. asthe descriptionproceedsthe' invention resides in'certain novel featuresof construction, and in the combination and arrangement of parts asWillbe hereinafter more fully described and claimed.

In the drawing The figure is a longitudinal vertical ,se ction throughthe apparatus.

Referring to the drawing in detail it will be seen that A indicatesgenerally the retort, having mounted therein the usual burn or B, andextending upwardly therefrom the usual stack C. A retort cylinder 5 ismounted across the top of the retort A and is provided with the gasescape openings or conduits 6 which Will lead to suitable condensingapparatus (not shown) but which is well known in this art. of steel ofsuch a quality as tobe nonwarping in spite of the intense heat towhic'hit is subjected. The burner B, of course, is

located immediately below the cylinder. and I extends longitudinallythereof. A shaft 7 is journaled longitudinally of the cylinder 5,andprojects beyond the end thereof. One end of the shaft 7 isoperatively connected This cylinder5 is made with a prime mover 8through a chain 9.- A

funnel lOleads into a cylindrical casing 11.v

In the upperend of the funnel 10 there is rotatably mounted a valve 12of cylindrical formation having anopening 13 adapted to bebroughtintoregistry with thelo'werend of the hopper 14L The shaft15 ofthe valve 12s opcratively connected with theshaft 7 by a chain 16. The shale isconveyed into the hopper 14 in any suitable manner, and

when the opening 15 registers therewith, the

shale will pour into the valve, and as the valve rotates,the shalepoured thereinto will 7 in a spiral alignment, and have paddles 21mounted on the ends thereof and extending obliquely tothe shaft 7. Asthe shaft 7 is rotating the shale is picked up from the bottom of thecylinder 5 by these paddles, and caused to circulate about theinteriorsur face thereof, at the same time being urged toward the outlet end ofthe tank. The shale from the tank 5 is finally poured through theopening 23 into the cylindrical casing 2 L communicating with ahopper26. A screw conveyor 27 isrotatable in the casing 24: and extendslongitudinallythereof so that the shale delivered to the casing 24 iscon veyed so as to pour into the hopper 26. The shaft of the screwconveyor 27 is operatively connected by a chain 28 to the shaft 7. Avalve 29, similar to valve 12,- is rotatable in a casing 30 at the lowerend of the hopper 26, and delivers the residue of the shale into theexhaust conduit 31. The shaft 32 of the valve 29 is operativelyconnected with the shaft 7 by a chain 33.

The vapors formed by the heating procnumber 66 shale through the retort,I oh tain an average of sixty gallons to the ton, While the Governmenttest only obtains forty-two gallons per ton, this experiment wasby'weight and liquid measure,

It is thought that the construction, opera- -tion, and advantages'ofthis inventionwill now be clearly understood by those skilled in thisart Without a more detailed description thereof. The present embodimentof the invention has been disclosed by Way of example since in actualpractice itattains the features of advantage enumerated as desirable inthe statement of the invention and the above description. It will beapparent thatchanges in the details of constructiomand in thecombination and arrangement of parts may be resorted to Withoutdeparting from the spirit or scope of the invention as hereinafterclaimed or sacrificing any of its'advantages,

Having thus described the invention, What I claim as new is:

1. An apparatus of the class described, in-

I eluding a retort comprising a burner, a cylinder extending across thetop of the retort above the burner, and having gas escape conduitsleading therefrom, a cylindrical casing leading into the upper portionof one end of the cylinder, andhaving a pair of openings,,one at thebottom thereof, interiorly of the cylinder, and the other at the topthereof, exteriorly of the cylinder, a funnel rising from said otheropening, a valve of cylindrical formation and having an opening, saidvalve being rotatably mounted in the upper portion of the funnel, ahopper rising fromthe funnel, conveyor mechanism in the cylinder, andmeans for simultane 'ously operating'the valve and the conveyormechanism. i

2. apparatus of the class described comprising a retort comprising aburner, a cylinder extending across the top of the retort above theburner and having gas escape conduits leading therefrom, a cylindrical'CEISHIg leading into the upper portion of one end; of the cylinder,andhaving a pair of openings, one at the bottom thereof interiorly ofthe cylinder, and the other at the top thereof exterior-1y of thecylinder, a screw conveyor rotatably mounted in the cylindrical casing,a funnel rising from said other opening, a valve of cylindricalformation and having'an opening, said valve being rotatable in the upperportion of the funnel, a hopper rising from the funnel, conveyormechanism in the cylinder, and means for simultaneously operating theconveyor mechanism, the screw conveyor and the valve.

3. An apparatus of the class described including a rctortcomprising aburner, a cylinder extending across the top of the re tort above theburner and having a gas escape conduit leading therefrom, a cylindricalcasing leadinginto the upper portion of one end of the cylinder andhaving a pair of openings one at the bottom thereof interiorly of thecylinder, and the other at the top thereof exteriorly of the cylinder, ascrew conveyor rotatably mounted in the cylindrical casing, a funnelrising from said opening, a valve of cylindrical formation and having anopening, said valve being rotatable in the upper portion of the funnel,a hopper rising from the funnel, conveyor mechanism in the cylinder, asecond cylindrical casing at the lower portion of the other end of thecylinder and having a pair of openings, one at the; bottom thereof eX-teriorly of the cylinder, and the other at the top thereof interiorly ofthe cylinder, a hopper leading downwardly from said other opening of thesecond cylindrical casing, a screw conveyor rotatably mounted in saidsecond cylindrical casing, a valve of cylindrical formation and havingan opening, said second mentioned valve being rotatable in th-e lowerportion of the second mentioned hopper, and means for simultaneouslyoperating the conveyor nechanisin, the two screw conveyors, and the twovalves.

In testimony whereof I aliix my signature.
